Code from: Spatial resource heterogeneity stabilizes local and regional predator-prey dynamics in ecologically-realistic networks

Spatial resource heterogeneity (SRH; the variable spatial distribution of resources) is a surprisingly understudied component of oscillatory consumer-resource dynamics. SRH may be particularly important in large, ecologically-realistic networks where different patterns of resource distribution can manifest, which has important implications for spatial synchrony. Here we explore how SRH in large spatial networks influences both local and regional consumer-resource stability. To do so, we employ a spatially-explicit Rosenzweig-MacArthur model and vary resource distribution accordingly: homogeneously-distributed resources of low, medium and high productivity, and heterogeneously-distributed resources. The latter includes networks with SRH of random variability in productivity (“random networks”) or a spatial productivity gradient (“gradient networks”). We analyze the effects of local patch factors (i.e., productivity and connectivity) and regional factors (i.e., productivity distribution a..., , , # Code from: Spatial resource heterogeneity stabilizes local and regional predator-prey dynamics in ecologically-realistic networks

## Description of the data and file structure

We simulated predator-prey dynamics in metacommunities using a spatially explicit version of the well-known Rosenzweig-MacArthur model (Rosenzweig and MacArthur, 1963). We have submitted Mathematica code (“SRM_Manuscript_2024.nb”) for model creation and numerical simulation, and two output datasets, one containing the results for the main manuscript (final.df.csv”) and one containing the results for the supplementary information (“all.data.for.supplement.csv”).
